Hey Yoshi, you said personal housing "will be far more affordable."

Now, I'm sitting on 197,826 gil and I can't make anything because the market on my server is garbage.

So don't make money off the markets...

Duty Roulette, just going off the Adventure in Need bonus, because I forget the regular Gil it gives;
Expert - 4,500 Gil. Alexandrite Map reward after that if you're that far in Relic quest, giving an extra 1,600 Gil (more but I'm rounding off memory).
High Level - 4,500 Gil.
Low Level - 4,500 Gil.
Trials - 2,700 Gil.
Main Scenario - 4,500 Gil.
Guildhest - 1125 Gil.

Beast Tribe Dailies;
Around 700 Gil per quests, 6 quests, 4,200 Gil reward.

Daily Hunt Mark Bills;
3,000 Gil in Hunting Log style kills.
4,000 Gil in FATE camping.

Daily Treasure Maps;
1,600 Gil ~ 5,000 Gil per map. Chance for a Unhidden Map, which is 10,000 Gil ~ 30,000 Gil - or you can sell it on the markets for a ridiculous amount.

Retainer Ventures;
OK, I can't be asked to work this one out - if you send them off on Explorations they bring back Allagan pieces, brings in a couple thousand Gil per Retainer, I'm sure.

That's well over 30,000 Gil a day, with the regular reward from Duty Roulette missing - it wouldn't even take you a week to double your Gil. I'm not saying do all of these things (unless you want to), I'm just pointing out that this game throws Gil at you if you know where to look. Heck, you can repeat the Duty Roulette ad nauseam to get the bonus all day long if you have the Jobs leveled. Guildhest is literally a couple minutes work for 1,000 Gil unless you get unlucky.
